Karin Junrei

Karin is regarded as the model of perfection among the girls at her school, admired by nearly everyone, including Kouji and Ikki. Her main hobby is cleaning, and she is known for her meticulous and composed nature. Despite excelling in almost every aspect, her cooking is notoriously poor—though no one dares to tell her.

Her Medabot partner is Neutranurse, a wing-type Medabot she treats like a sister, and who is also known as the legendary Medaguerrera. Karin is the niece of Dr. Aki.
